It achieves CO2 readings of 347g/km and is 15% more efficient than the first version of the GT Speed. It weighs 175kg more than the current hard top GT Speed. The improvements in efficiency have led to an increase of 15% in the vehicle's range.

Both the convertible and the hard top version are fitted with an eight-speed ZF automatic gearbox to help drivers make smooth and quick changes in speed.

The car is expected to cost around £160,000, and drivers are also advised to invest in comprehensivecar insurance .
